$PECIFICATION forming part of Letters Patent No. 626,725, dated June 13,1899. Application filed June 30, 1898. Serial No. 684,873. (No model.)

To all whom it may concern.-

Be it known that we, JAMES W. SooTT and EARNEST A. ScoTT, citizens ofthe United States, residing at Marion, in the county of Marion and Stateof Ohio, have invented a certain new and useful Improvement inExcavating-Machines Operated by Traction,'of which the following is aspecification.

Our invention relates to excavating-machines operated by'traction,especially ditching-machines, and has for its object to provide astrong, simple, cheap machine of few parts, having'an adjustabledouble-plow attachment and carrier or elevator for receiving anddisposing of the loosened earth in a rapid and perfect manner, saidmachine being practical, capable of operation with minimum draft, andadapted to adjust the working parts to the progress of the work and theincreasing depth of the excavation. This object we accomplish in themanner and by the means hereinafter fully described in detail 4 andparticularly pointed out in the claims,

reference being had to the accompanying drawings, in which like figuresindicate like parts in all the views.

Fig. 5 is a view of elevator on line m 00, Fig. 4.Fig. 6 is a detail View of scoop. Fig. 7 is a detail View of hubs'andfastenings. Fig. 8 is a detail view of chain, canvas, cross-piece, andbrackets. Fig. 9 is. a detail view of loop and attachments. Fig. 10 is atop' plan view of loop and attachments. Fig. 11 is a detail view oflever and toothwheel. Fig. 12 is a detail View of hole and coupling.

Our invention consists of two side beams 1, having cross-pieces 2between them, one near each end and one in the middle, through whichthey are bolted. The front cross-piece 2 is pivotally secured by a boltto an axle 3 on two wheels having the draft 4 immediately under the endsof the side beams 1, a brace running from the under side of the centercross-piece 2 to the bolt under the'axle, where it is secured. On theside beams 1, near the front, a drivers seat 5 is provided. Bolted tothe outside of and rising vertically from one of the side beams 1,within reach of the drivers hand, is a standard 6, on top of which abearing 7, provided with the usual lubricating devices, is secured. Ashaft 8, j ournaled in said bearing 7, carries on its inner end acrank-wheel 9 and on its outer end a small sprocket-wheel 10. The rearof the side beams l rests on a metal hub 13, inclosing a heavy iron orsteel axle 14, carried by large and strong wheels 15, and the side beams1 are each firmly secured to said axle 14 through the hubs 13 by metalstraps 16 and tie-rods 17. Just forward of the rear axle 14, on theinside of each of the side beams 1, is a standard 18, inclineddownwardly diagonally toward the front and securely bolted to the sidebeam 1 through a metal plate 19, placed on the outside ofeach sidebeam 1. Between the standards 18 are two slides 20, provided on theoutside with guides 21, complementary to the inside formation of thestandards 18. The slides 20 are held in place by suitable crossbars 22,preferably of square metal bars, shoul-,

dered near their ends, which pass through the slides 20, and then havenuts screwed on them, two at a suitable distance from the top and two ata like distance from the bottom, one on each side. The slides 20 alsohave slots 23 running longitudinally from just below the uppercross-bars 22 to just above the lower cross-bars 22. Two shafts 24, onenear the top and the other at a like distance from the bottom, havetheir ends j ournaled in said slides 20 and extend across between theslides 20. These shafts 24 each carry two sprocketwheels 25, one on eachside next the slides 20. A large cog-wheel 26 is mounted on the rearaxle 14 on the side of the side beams 1 opposite that on which is thestandard 6. This cog-wheel 26 meshes with a pinion 2'7, mounted on theend of a shaft 28, passing through the metal plate 19, side. beam 1,standard 18, slots 23, and the other standard 18 and side beam 1,suitable bearings being provided. This pinion-shaftv 28 carries twosprocketwheels 29, one on each side just inside the slides 20, andchains 30 connect these sprocket wheels 29 with the sprocket-wheels 25.piece of canvas 31 or other suitable material for excluding dirt isplaced on chains 30, and upon the canvas 31, at suitable intervals, areplaced cross-pieces 32, which are secured by boltsor clamps to thechains 30. Elevatorbuckets 33 are bolted or otherwise suitably securedto the cross-pieces 32. A shaft 34 has one end journaled in the standard18 on the side of the pinion 27, passes through the slots 23 andopposite standard 18, and is furnished at its projecting end with asprocketwheel 35, which is connected by a chain 36 with thesprocket-wheel 10. To a movable collar 37 on shaft 34 one end of a chain38 is securely fastened, the other end of the chain 38, after beingpassed through a pulley 39, attached to one of the lower cross-bars 22,being rigidly fastened to the shaft 34. An open-mouth trough 41 isplaced transversely across the side beams 1, just behind the standards18, and inclined slightly upward toward its closed end, its higher endsupported by a brace bolted to the side beam 1.

Rising from the rear side of the trough 41, behind the standards 18 andslides 20, is a flanged screen 43, supported on each side by a V-shapedbrace, its open, ends secured to one of said flanges and one side nearthe apex bolted to the standard 18 at its top.

Extending forward from the slides 20 011 each side and securely boltedthereto is a piece 44, of plate or boileriron or other suitable materialof proper size, the forward ends of the pieces 44 being connected by acrosspiece 45, of like material, having angled ends securely bolted tothe pieces 44. Extending across between the pieces 44 and securelybolted to them is the metallic scoop 46, which receives the dirt fromthe plow 47 and delivers it to the buckets 33. Two metal bosses 48 ofproper size, provided with screw-threaded holes through their centers,are securely bolted at a suitable distance apart to the inside of eachof-the pieces 44, the holes in the bosses 4S registering with like holesin the pieces 44. Working in the holes through the bosses 48 are heavymetal screws 49, to the inner ends of which are attached toothed wheels50 and to the outer ends of which are secured metal plates 51. To theoutside of eachof the plates 51 are fastened a colter 52 in front and aplow- 47 behind. The toothed wheels 50 are provided with levers 53,having. dogs 54, adapted to engage the toothed wheels 50 in eitherdirection. The two levers 53 on each side are connected by a bar 55, andthe two levers 53 behind are longest and serve as handles to operate thetoothed wheels 50.

The operation of our invention is as follows The levers 53, ,by means ofthe two in the rear, are used to turn the toothed wheels 50 untiltheplates 51, carrying the colters 52 and plows 47 with them, arefarthest apart, the slides 20 being lowered by the driver as the machinestarts by the crank-wheel 9 sufficiently to'enable the plows 47 to takegood hold. As the machine moves the plows 47 throw the dirt toward themiddle upon the .scoop 46 until it is pushed up and over and the buckets33 receive it. The rear axle 14 revolves the large cog-wheel 26, whichturns Y ter conducts the dirt off to one side. i a sufficient distancehas been traversed, the

the pinion 27 in the opposite direction, and through the pinion-shaft28, sprocket-wheels 29,- chain 30, and sprocket-wheels 25 raises thebuckets 33 and empties them backward upon the screen 43 and trough 41,which lat- When driver raises the slides 20 by means of the crank-wheel9, turns the machine, lowers the slides 20 in the same way until theplows again take hold, and, retracing the furrow already made, deepensthe excavation, throwing the dirt this time on the opposite side fromthe first. These operations are repeated until the excavationissufficiently deep. If the soil is loose or if for any other reasonstraight sides are not desirable, the colters 52 and plows 47 may ateach successive operation be brought nearer together by means of thelevers 53, forming a ditch with sides like steps.

Having thus described our invention, what we'claim as new, and desire tosecure by Letters Patent, is
